[Lldb-commits] [PATCH] D12746: The pipe2(2) call is supported on NetBSD

[Pavel Labath via lldb-commits]

I think the main reason behind it is that we have about three build
systems. Any check you write will need to be implemented in all of
them. Maybe when autoconf goes away, we can do a build check in cmake
and xcode can just hardcode -DPIPE2_SUPPORTED=0, since it is only used
on darwin anyway.
